Letters Patent No. 107 ,5 7 1, dated September 20, 1870.

IMPROVEMENT IN CAR-COUPLINGS.

The Schedule xexerred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, WILLIAM WALKER, of Woodsrde, county of San Mateo, State of California-,have mvented an Improved Gar-Ooupling'i, and I do hereby declare that the following is a full, clear, and

exact description of the same, reference being had-to the. accompanying drawing and to the letters-marked thereon.

My invent-ion relates to certain improvements in that class of car-couplings which is operated automatically, whereby the cars, when brought together, will become coupled by the impact, without the intervention of ,an attendant; and further relates to a device by which the said cars may be uncoupled from the side or top, by means of a'chain or rod leading to any desired position.

The object of myinvention is to facilitate the coupling together of trains of cars without danger to life or limb, and to facilitate the uncoupling of the same by an attendant on top or at the side of said cars.

In the drawing- 7 Y Figure 1 is a side elevation.

Figure 2 is an end view of a car-coupling embodying my improvements.

To enable others skilled in the art or science to which it most nearly appcrtains to make and use my invention',1 will proceed to fully describe its construction and operation.

A is the bumper.

B is the coupling-pin, secured to the vertical sliding frame 0 by the key D.

E is a slidingbolt, provided'with a suitable spring, F, shown in dotted lines, and also provided with a stop-lug or projection, G.

H H are guides for the frame 0.

I, av handle, forming part of the frame 0. To this handle suitable chains or rods may lead to the top of the car, or be attached to the side by means of a pulley, bell-crank, or lever. i .Jis'aspring.

The-drawing represents the position of the parts when the ears are coupled, the car, not shown, having the usual link secured in the usual manner, said link being secured to the coupling having my improvement by means of the pin B,'the pin B and frame 0 being held down'by the spring J.

Now, if we grasp the handle I and draw the frame 0 upward until the notch K comes opposite the stop G, the spring F will cause the bolt E to move up ward and project beyond th'efacc of the bumper, and the lug or stop G would prevent the frame from being drawn downward by the spring J when we let go the handle I, and the bolt or coupling-pin B would have been drawn up so as to release the link, and, consequently, the uncoupling would have been eflected, and theapparatus ready set for automaticallycoupling the next car, by the impact of the bumper of said car with the projecting end of the sliding bolt E; and said sliding bolt would be forced back by said impact with the stop or lug G passed out of the notch K,

when the frame 0 wonldbedrawn by the spring J to the position shown in the drawing.

Having thus described my invention,

What I claim, and desire tosecure by Letters Patent, isp The car-coupling described, consisting of the drawhead A, pin B, frame 0, sliding bolt E, with projection G, and spring J, when the parts are combined and arranged as described.

In testimony whereof I have hereunto set my hand and seal.
